In orienteering there are times when it is forbidden to cross certain symbols that have been used to depict the ground on the map. This is different depending on whether the map is made according to ISOM specifications for forest orienteering or ISSprOM for sprint orienteering.
The Orienteering Australia Competition Rules cover this in section 17 of the rules.
17. Restricted areas and routes
17.1 Rules set by Orienteering Australia or the organising Association to protect the environment and any related instructions from the organiser must be strictly observed by all persons connected with the event (see Environmental Guidelines – Appendix 7).
17.2 Out-of-bounds or dangerous areas, forbidden routes, line features that must not be crossed, etc. must be marked on the map. Where they are not obvious to the competitor, they must also be marked on the ground.
Competitors must not enter, follow or cross areas, routes or features drawn with the following symbols:

17.3 Compulsory routes, crossing points and passages must be marked clearly on the map and on the ground. Competitors must follow the entire length of any marked section of their course.
In Tasmania, many of our older maps have not been updated to the latest ISSprOM specifications. Competitors need to be aware that they may be disqualified if they cross a forbidden feature. Organisers are permitted to disqualify orienteers who breach the rules on restricted areas and routes after the results of an event are finalised. Such disqualifications may be based on evidence such as split times, GPS routes, complaints from other persons. Before this provision is used, the organiser must give the orienteer right of reply (e.g. by email).

As soon as possible after running an event (even before you leave the site if you have the energy and mobile coverage), use the Backup option in SiTiming, and email the backup (a zipped folder) to results@tasorienteering.asn.au

The backup is eagerly awaited by Ian and Jeff.

1) Ian (or possibly Jeff) will do a quick check of the results and export them to upload to Eventor. The splits information is automatically linked from there to Winsplits and Livelox, adding much detail for the debriefing and post-run revelries.

2) Ian archives the backup

3) Jeff processes OST and Excellence points, providing confusion and grief to the few nerds who care about them.

The following article from John came from his Controllers Corner Nov 2009

Let’s face it – we’ve all done it at some stage at some event somewhere. We’ve talked to someone when out orienteering – probably to ask for help or a location. And that it is against the rules!
Well – not quite. The rules don’t specifically forbid talking to others in the forest, but they forbid requesting and /or giving assistance. Let’s look at what they actually say:

26. Fair play
26.1 All persons taking part in an orienteering event shall behave with fairness and honesty. They shall have a sporting attitude and a spirit of friendship. Competitors shall show respect for each other, for officials, journalists, spectators and the inhabitants of the competition area. The competitors shall be as quiet as possible in the terrain. Competitors or spectators shall not interfere with control equipment.
26.2 Except in the case of an accident, obtaining assistance from other runners or providing assistance to other competitors during a competition is forbidden. It is the duty of all competitors to help injured runners.
